CALCULATINGr-MAGHINE.

Specification of Letters Patent.

Application led February 17, 1914. Serial No. 819,224.

lowing is a specification.

My invention relates to improvements inl calculatingmachines, and more particularly in calculating machines of the class in which the setting mechanism consists of setting disks each of which is provided with nine teeth representing the values to be set on the disks and of cam disks for setting the desired number of teeth into operative positions, so that when rotating the setting disks the number corresponding to the shifted teeth is transmitted to a registering mechanism. In machines of this class the carrying mechanism consists of additional teeth provided on the setting disks and adapted to be shifted into operative position by means of rocking levers or hammers adapted to be operated by the numeral wheels. The additional teeth provided on the setting disks thrown into or out of operative positions same in radial direction or by rocking the same laterally by means of the said rocking hammers, which for this purpose are equipped with cam faces adapted when in operative posit-ions to be engaged by the carrying teeth. Carrying mechanisms of this tvpe are shown in the patent of the United States No. 928,083, granted to Franz Trinks J mayv 13th, 1909.

In the setting disk of the second order two carrying teeth must -be provided one for right hand and the other one for left hand operation of the setting disk, and the teeth must be disposed at such a distance from the that when rotating the setting disks at rst the rocking member or hammer is rocked into operative position, and that thereafter the carrying tooth gets into engagement with the cam face provided thereon, and as two carrying teeth are provided on the setting disk the circumference of the setting disks is increased by the double path of the disk required for this o ration. Furthermore the carrying) teeth o the consecutive setting disks must e dislaced relatively to each other in such a way, .that 4each time the carrying tooth of for performing the carry-l either by shifting thev one disk is advanced relatively to the tooth of the setting' disk of the next lower order a distance corresponding to the pitch of the value teeth of the setting disks, because the carrylng tooth of a setting disk can not be brought into engagement with the cam face of the cooperating rocker or hammer, before the carrying tooth of the setting disk of the lower order is out of engagement with the coperating numeral wheel or intermediate gear wheel, and the rocker orhammer has been completely set in operative position. If the said distances are less than what has been described, it 'may happen, that the carrying teeth are not engaged any more by the hammers which have been rocked too late, and therefore remain inoperative, so that they are pressed from the side against the teeth of the adjacent numeral wheel or intermediate gear wheel instead of gettinginto engagement therewith. By thus displacing the carrying teeth relatively to each other the circumference and the diameter of the setting disks are increased, which is objectionable because thereby the said disks are in a higher degree liable to be overthrown.

The object of the improvements is to provide a carrying mechanism in which the circumference and the diameter of the setting disks are comparatively small.

Vith this object in view my invention consists in so constructing the carrying mechanism that the carrying levers are constantly located with their cam faces at the rear of lateral noses of the radially shiftable carrying teeth, so that the carrying teeth can be shifted outward and into carrying position when they have already arrived in position for engagement with the cooperating intermediate gear wheels. Furthermore it is not necessary in this construction, that the carrying lteeth of the setting disks of the second order away from the shiftable teeth, but they can be disposed immediately adjacent to the said teeth. Thereby the diameter of the setting disks is materially reduced, without interfering with the proper operation of the carrying mechanism.

-For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawings, in which the same letters ofreference have been kusedin allthe views to indicate correspondingA parts.
